Abstract: A device for thermoplastics melt impregnation of nature fibers was developed. Long jute fibers reinforced high density polyethylene was prepared by the mold impregnation process. Effects of fiber content and impregnation temperature on mechanical properties and microstructure of the composite were studied. When the loading of jute fibers was 45 % and impregnation temperature was 210 ℃, the tensile strength was increased by 49.1 % and the flexural strength was increased by 137 %.

Key words: high density polyethylene, jute fiber, melt impregnation, composite
